Original AM Micropower Transmitter. The picture to the left is a high quality radio transmitter for the A.M. broadcast band. The transmitter legally operates with "micro-power" and will not set any distance records but, unlike simpler designs, the frequency stays put and the fidelity is excellent.A liquid cooling system cools a plurality of RF power amplifiers utilized in a high power AM broadcast transmitter. Each RF power amplifier includes a thermally conductive block to which the power transistors associated with that amplifier are physically mounted.
This AM has not been on the market in years. It is a good, solid signal serving the DFW metro area. Real estate at the transmitter site and all equipment is included. It is an impressive operation. Serious inquirers only, please. Nondisclosure is required. Using Solid State Rigs on AM. The best "solid-state" rigs for AM audio fidelity, would have to be the Kenwood TS-850, and the older hybrid Yaesu FT-102. Both of these rigs have been known to have the "best" AM audio out there of a ricebox, and often sound much better than the older boatanchors..
Jan 31, 2014 · The plugin solid-state rectifiers are removed. The change to switching both the high and low (to selected stages) B+ necessitated a change in the way the function switch operates. I thought about this for quite awhile, tried many schemes, and finally came up with rewiring the switch and using diodes to achieve the desired result.
Capable of working in AM, SSB, and PA modes, this forty-channel mobile transceiver has advanced noise filters and blankers, five-digit frequency display, built-in meter with four scales, automatic SWR circuit, 3-position tone control switch, and plenty of other features. When it comes to radio transmission, Broadcast Electronics' FM transmitters are hard to beat. Standout features include true proportional VSWR foldback for transmission resiliency and independent IPAs and power supplies that give you full standby power without having to buy another transmitter..

Pressure transmitters can produce several types of electrical signals, including analog voltage and analog current. These output signals can be encoded via amplitude modulation (AM), frequency modulation (FM), or some other modulation scheme such as sine wave or pulse train.
Redmond: GatesAir (and Harris before it) has been building solid-state transmitters for more than 40 years. In fact, some of our first solid-state AM transmitters are still in service. The company’s philosophy of design is the foundation of every transmitter we build, including today’s high-power systems for UHF digital TV.
The TR-6000 is a solid-state, class D AM transmitter specially designed for traveler’s information, carrier current, roadside radio, and other low-power broadcast band AM applications. with the home brew AM transmitter (albeit solid state screen modulated) was on December 23. That modulator worked for many mostly local contacts, but it was never good for more than about 25 watts carrier input and 70% modulation. The 1964 edition of the ARRL Handbook described a better companion modulator for the
